I recently purchased a Onefinity Foreman and after trying to update firmware the HMI experienced a black screen with a cursor. I tried rebooting and continued to get a black screen. Looking through the forums I found how to reflash the OS and followed the instructions making sure I downloaded the correct file and used a fresh SD Card. When I re-installed the SD card and turned on the HMI it is in a rebooting loop that I let go for about 30 minutes. It flashes between Initializing hardware interface and Initializing game controller continuously but never loads the OS. Is there anything I can try to fix?

I would also reach out to Onefinity and RealTime CNC if you have not already done so.
